• ArF*, KrF* and XeF* emissions produced from dissociative ion recombination reactions of Ar+, Kr+ and Xe+ with SF6− in the flowing afterglow

  The ArF*, KrF*, and XeF* emissions resulting from dissociative ion recombination between rare gas cations and SF6− anions have been studied in the flowing afterglow. The anions were formed by thermal electron capture by SF6. The KrF* product state distribution from the two Kr+(2P32,12) spin-orbit states showed that the B and C states are preferentially formed by the Kr+(2P32) reaction, while Kr+(2P12)

  Sensitized reactions of Xe and Kr with halogen donors in the presence of high buffer gas pressures of Kr and Ar, respectively, have led to the observation of five emission bands in the ultraviolet region of the spectrum. These broad structureless bands are assigned to the mixed rare gas–halide trimers KrXeCl, KrXeBr, KrXeI, ArKrF, and ArKrCl. Despite an extensive search, no emission corresponding to KrXeF could be found and this mixed trimer may be unstable because of interaction with a lower repulsive state. The positions and half-widths of the five emission bands are characterized, and the formation mechanism of the mixed trimers in these experiments is discussed.

• Photodissociation of Kr2F(4 2Γ) in the ultraviolet and near-infrared: Wavelength dependence of KrF (B 2Σ) yield

  The photoabsorption spectrum of the 4 2Γ excited state of Kr2F has been measured in the 280–850 nm region by fluorescence suppression spectroscopy. Both the 9 2Γ←4 2Γ and 6 2Γ←4 2Γ bands, peaking at 320 and ∼710 nm, respectively, have been observed—the latter for the first time. Although the position of the ultraviolet band is consistent with both theory and previous experiments, its spectral width is ∼40% of that measured by Greene and McCown [Appl. Phys. Lett. 54, 1965 (1989)] in absorption experiments in a pulsed discharge. The relative yield of KrF(B) produced in the photodissociation of Kr2F(4 2Γ) was found to be independent of wavelength over the 280–360 nm and 590–840 nm spectral intervals and the mechanism responsible for photodissociation appears to be predissociation of the Kr2F 9 2Γ and 6 2Γ states by potentials correlated with the KrF(D)+Kr and KrF(C)+Kr limits, respectively.
• Excitation spectra for the photoassociation of Kr–F and Xe–I collision pairs in the ultraviolet (208–258 nm)

  Photoassociation, the bound←free absorption of a photon by a colliding pair of atoms, has been studied experimentally in the Kr–F and Xe–I systems and is demonstrated to be an effective tool for deducing molecular interaction potentials and for determining the dependence of the relative electronic transition moment on internuclear separation (R) in small molecules having dissociative ground states. Specifically, the excitation (‘‘action’’) spectrum for the photoassociation of thermalized Kr(4p6 1S0)–F(2p5 2P) collision pairs, measured at 300 K in the 208–250 nm wavelength region, reveals deeply modulated Franck–Condon structure associated with transitions of Kr–F pairs from the ground state’s thermal and vibrational continua to the lowest 27 bound vibrational states (v′=0–26) of the KrF(B 2Σ) excited state. Under these conditions, photoassociation occurs in a narrow (ΔR=0.7–0.8 Å) Franck–Condon region in which the difference potential is a single valued function of R. Similar spectra have been observed for Xe(1S0)–I(2P) pairs in the 208–258 nm spectral region that arise from bound←free transitions to the lowest ∼40 vibrational levels of the XeI(B) state. Since the Kr–F and Xe–I collision pairs are photoexcited from the vibrational continuum of the ground state, the atomic pair energy distribution is thermalized and the envelope of the excitation spectrum can be interpreted directly in terms of the relative B–X transition moment, μ(R). Consequently, the behavior of μ(R) has been determined over a limited range in R and, for XeI, μ is found to fall by a factor of 2 in the ∼0.4 Å region extending from R−ReB≊0.25–0.62 Å. The XeI ground state (X 2Σ1/2+) potential in the 3.0≤R≤5.0 Å interval, derived from photoassociation spectra, is similar to that deduced from scattering experiments. Excited and ground state structural constants derived from numerical quantum simulations of the experimental spectra are presented.
